The island of Kos is located in the southeastern Aegean Sea. Earthquakes and associated phenomena such as tsunamis have been recorded in the region since the antiquity with the latest catastrophic earthquake being that of 1933, with a magnitude of 6.6 R. that destroyed the city of Kos claiming the lives of 178 people. Based on the Civil Protection Frame that applies in Greece, all the available scientific and technical data for the municipality of Kos were collected and analyzed in order to conduct an earthquake and a tsunami emergency plan. The proposed plan includes a contingency plan for the Local Authorities, emergency maps as well as guidelines for emergency drills and public information.
